1) For a computer, a CRT terminal or printer. 2) For a programmable controller, see actuator
Industry:Automation
In paint programs, a collection of drawing tools, such as geometric shapes, patterns, colors, brush shapes, and line widths, from which the user can choose.
Industry:Automation
In programming, a signal that is used to govern access to shared system resources. A semaphore is a flag variable — an indicator — that helps maintain order among processes that are competing for use of such critical resources as microprocessor time and communication ports. See also flag
Industry:Automation
The process of breaking up a continuous variable into discrete quanta or parts.
Industry:Automation
A link topology in which all stations are connected in parallel to a medium. These stations are capable of concurrently receiving a signal transmitted by any other station connected to the medium.
Industry:Automation
1) For dc drives — the characteristic of a motor to act as a generator when the cemf is larger than the drive’s applied voltage. 2) For ac drives — when the rotor synchronous frequency is greater than the applied frequency.
Industry:Automation
The process of comparing an instrument or device with a standard to verify its accuracy, to make adjustments to meet the standard, or to devise a corrected scale.
Industry:Automation
The process of controlling and monitoring data table bits, bytes, or words by means of the user program to vary application functions.
Industry:Automation
1) Having to do with the actual time during which physical events take place. 2) The performance of a computation during the actual time that the related physical process transpires so that the results of the computations are useful in guiding the physical process.
